Abstract
A frequency switching terminal is provided to input a signal for switching frequencies of a reception circuit. A smart ECU is connected to the frequency switching terminal via a connection cable. When the signal for switching the frequencies is inputted into an external input terminal of the reception circuit from the smart ECU via the frequency switching terminal, the reception circuit receives a first electric wave transmitted from a portable terminal for smart entry. In contrast, when the signal for switching the frequencies is not inputted into the external input terminal of the reception circuit from the smart ECU via the frequency switching terminal, the reception circuit receives a second electric wave transmitted from a tire sensor.
